Due to the location and if it really is a FITH replacement, a fire company theme is pretty much guaranteed. I think it will be a generic "towns on fire" theme. Maybe they will lightly mention the baldknobbers, but they probably wont have any hoods.
The real question is how they will approach the ride system itself. Is is going to be thrilling, or more of a dark ride? Aimed at allowing younger kids, or will they do something crazy that raises the height limit? Will there be a world's first? Will it be reliable, or break down continuously?
Personally I'm hoping that it is true to the original with lots of practical effects and props during a long slow dark ride section followed by the classic fire in the hole drop at the end. Keep it relatively simple so that kids can ride and it doesn't break down every hour.
